Hi,

I'm in the process of building up my new slot droout frame and have run into a few problems fitting the rear brake.

The kit is as follows;

DMR revolver rear singlespeed hub
Avid 185 rotor
Hope mono mini caliper

It all worked fine on my previous frame (summer season) although I was using 160 to 185 adaptor, I've tried using the same adaptor on the slot dropout, but it doesn't fit and have tried without and it's still way out.

Do I need a new adaptor or something? I've heard ghat revolvers have certain rotor compatibility problems, could this be it.

Any help would be greatly appreciated.

Dave
